I'm trying to change password to login on remote server. For example from pas1 to pas2.

I use passwd command. The result is successful: I see "The NIS password has been changed" and if I try passwd command one more time the pas2 is accepted as old password for passwd command. But, when I try to relogin I has to use pas1.

How to change the login password?

What is the exact command your using? the command takes some arguments mainly the username the password belongs to. – Ramhound Dec 7 '12 at 14:02
Could be a straight UNIX server too, they tend to behave a bit differently with the passwd command. Do you know what the server is running (beyond just linux)? – nerdwaller Dec 7 '12 at 14:11
Ramhound, "passwd" – klm123 Dec 7 '12 at 15:07
Type alias passwd to see whether you’re maybe running something other than passwd. Then type ls –l /bin/passwd to see whether it’s a symbolic link to something. – Scott Dec 11 '12 at 2:17
